Physics in Our Daily Life

What is Heat Transfer?

The movement of thermal energy from a hotter object to a cooler object through conduction, convection, and radiation.

What is Conduction?

Heat transfer through direct contact.

What is Convection?

Heat transfer through the movement of liquids or gases.

What is Radiation?

Heat transfer through electromagnetic waves.

Physics in Refrigeration

Concept: Thermodynamics. Application: Removes heat from inside the refrigerator and releases it outside.

Physics in Washing Machines
